What suctioning times are recommended for infant, child, and adult?

• A. Infant 5 seconds; Child 15 seconds; Adult 10 seconds
• B. Infant 10 seconds; Child 5 seconds; Adult 15 seconds
• C. Infant 15 seconds; Child 10 seconds; Adult 5 seconds
• D. Infant 5 seconds; Child 10 seconds; Adult 15 seconds

Answer: (D)

The idea here is to balance clearing secretions with keeping enough oxygen in the patient. Suctioning tends to remove air and can cause rapid desaturation, so the duration is kept as short as possible for each age group.

Infants desaturate quickly and have very small airways, so a brief suction pass—about 5 seconds—is enough to clear material without giving the body a chance to become hypoxic. Children can tolerate a bit longer clears, around 10 seconds, which helps remove secretions more effectively in their larger airways while still protecting oxygen levels. Adults have the largest airways and greater oxygen reserves, so up to about 15 seconds is acceptable to clear stubborn secretions without excessive desaturation.

In practice, always pre-oxygenate if you can, monitor the patient’s color and vitals, and stop early if signs of hypoxia or bradycardia appear. If more suctioning is needed, pause to reoxygenate and ventilate between attempts.
